Abstract The current study was conducted to examine the role of lexical cohesion in improving quality twelfth graders’ essay writing. specifically aimed at examining correlation between cohesive devices (LCD) and written texts as well investigating barriers employing these for graders. context a private American curriculum school UAE. present paper adopted quantitative correlational survey rese...

The computer represents a new resource in developing social capital that previously did not exist among migrants. The relationship between physical space and cyberspace is discussed using the experience of migrants from Newfoundland who, although dispersed from their homeland, use the computer to maintain ties with both their homeland and others in diaspora. Three phases in the migration cycle ...

In finite element analysis (FEA) models of cemented hip reconstructions, it is crucial to include the cement-bone interface mechanics. Recently, a micromechanical cohesive model was generated which reproduces the behavior of the cement-bone interface. The goal was to investigate whether this cohesive model was directly applicable on a macro level. From transverse sections of retrieved cemented ...

Finite element calculations of dynamic fracture based on embedding cohesive surfaces in a continuum indicate that the predictions are sensitive to the cohesive law used. Simulations were performed on a square block in plane strain with an initial edge crack loaded at a constant rate of strain. Cohesive laws that have an initial elastic response were observed to produce spontaneous branching at ...

Despite many successes with teleoperated robotic surgical systems, some surgeons feel that the lack of haptic (force or tactile) feedback is detrimental in applications requiring fine suture manipulation. In this paper, we study the difference between applied suture forces in three knot tying exercises: hand ties, instrument ties (using needle drivers), and robot ties (using the da Vinci™ Surgi...

The social networks literature suggests that ties must be maintained to retain value. In contrast, we show that reconnecting dormant ties—former ties, now out of touch—can be extremely useful. Our research prompted Executive MBA students to consult their dormant contacts about an important work project; outcomes compared favorably to those of their current ties. In addition, reconnecting previo...
